1997 7.3 won't cold start

When I plug my truck in it starts fine but when i leave it unplugged overnight (regardless of temp it seems) it cranks and cranks until it finally starts turning. Lots of white smoke, just replaced my glow plugs and injectors but its still doing it. Any ideas?

replaced rely too. you can see the battery go down down when you hear it click on the tach so I know thats working. And its running really good once I get it started so I really don't think it's compression. and thanks!

It really sounds like a glow plug system issue. Like said relay or UVCH's bad new glow plugs or its not turning relay on something.
